Are you in California and wondering whether a prosthetic or wheelchair could help your amputee dog or cat? A pawesome group of biomedical engineering students want to help you find out.
It doesn’t matter which limb is missing, or how much residual limb your pet has.
Engineering students at the University of California at Berkeley are once again actively looking right now for five or six amputee pets to participate in their unique, safety-first pet prosthetics project.
In a repeat of last semester’s project, this time it’s led by Ramzi Hreish, a mechanical engineering major at Berkeley. His colleagues are a bioengineering major and a computer science double major. The three are participating in Berkeley’s 3D Printing for Prosthetics course to build free prosthetics for animal amputees.
The students are partnering with real-world animal prosthetics innovators to design and fabricate free custom prosthetics for a small group of lucky Tripawds this semester.

What the Berkeley Team Is Offering
In collaboration with industry leaders like 3D Pets, the design team is seeking five to six California-based Tripawds, ideally in or near the San Francisco Bay Area.
This is a semester-based project with a rapid turnaround. Candidates are being reviewed now. Here’s what they want you to know:
The class has a capacity of 5–6 patients, so unfortunately we cannot guarantee selection. However, we believe it’s of utmost importance to present each case to our students as thoroughly as possible, and all the information we ask for in the form helps us do that.
- If you are not selected this year, you may choose to be automatically placed on the waiting list for the following semester.
This course is run by, and taken by, students with varying levels of expertise in the field. The students are taught by students who have succeeded in the course in the past.
A panel of experts in fields that span prosthetic design, mechanical engineering, materials engineering, and more is advising the group.
Leader Ramzi Hreish tells us:
“We cannot guarantee industry-grade results, but we treat every project with the belief that our responsibility is to care for and help these patients as if they were our own.
Everyone in the course has some relationship to animals and an interest in different areas of the biomedical field, so it’s in their interest, and ours, to produce the best result we can in the time allotted.
We kindly ask that you be patient with us and with this course, and trust that we have your patient’s best interest at heart.
In some cases, projects have continued past the semester when students hadn’t yet finished a prosthetic they were satisfied with, but still wanted to complete their patient’s case, finalizing the work over the next semester.

Why Tripawds Is Supporting The UC Berkeley Pet Prosthetics Project
This is not a casual DIY experiment because someone has a 3D printer.
At Tripawds, we firmly believe that no pet prosthetic should ever be designed without expert input.
We are excited about this effort because it’s a high-level, expert-driven project that prioritizes animal safety and comfort while advancing prosthetics research for both animals and humans.
The students have and bring in loads of expertise in 3D-printing and additive manufacturing.
All prosthetics and assistive devices produced in the course undergo a comprehensive safety and design review by independent volunteers who work professionally as engineers and clinicians
